Looivr non WEAVING WHEREIN THE wnrfrs ARE nnawn FROM sTATIoNARYSUPPLIES.

Application filed May 4, 1925, Serial No. 27,883, and in Great BritainMay 5, 1924.

This invention relates to the-mechanism for operating the weft threadslin looms for weaving wherein the wefts are drawn from stationarysupplies and such mechanism is specially applicable. for use with theinvention set forth in our prior British Patent No. 168,444 dated J une14, 1920, but it must be understood that the present invention is alsoapplicable for use with other classes of looms for weaving wherein thewefts are drawn from stationary supplies.

The present invention will be described as applicable to the machine setforth in our prior patent, and will be fully understood from thefollowing description aided by the annexed drawings.

Figure l is a side elevation of a portion of a loom frame with two ofour reciprocating rods or tubes carrying weft threads and also showingcooperative selvedge shuttles and their carrier, the reciprocatory rodsor tubes being in the starting position for applying the weft threadsacross the fabric.

Figure 2 is a plan of the two reciprocating rods or tubes and thecooperating shuttles and their carrier shown in Figure l.

Figure 3 is a side elevation of a selvedge shuttle and its carrier.

Figure 4 is a plan with a portion of the carrier broken away to show theselvedge shuttles.

7We employ singly or in multiple, as required, rods or tubes or pairs ofmultiples of pairs of lods or tubes (in the drawings we show a pair 28,28) positioned parallel and each or each pair or the whole are connectedat or near the outer end to a device comprising a sleeve A or carriageslidable upon a bar or bars orl track or tracks 52, to preventrevolution, such device A or devices being reciprocated by any desiredmechamsm.

At the inner end of each rod 28 we pivot, in rule joint fashion, an armB havingan eye or roller 3l or other means for carrying a weft thread29. lThe warp threads are shown at P.

Each weft thread is run from a reel 34, constituting a stationary weftsupply, over rollers C, 1 one of which, C1 is capable of being bralredto apply tension to the thread, and then around a roller or rollers D oreyes on the rod 28 to the eye or roller 31 in the arm B and connectedwith the material E from which, for example, a door mat is being made.

Each shuttle 36 is formed with a curved nose piece F and with extensionpieces G at top and H, H at bottom and each shuttle is also curved onone side, and such shuttles 36 are positioned in a casing J having anopening N along the top froinfront torear and also having an openin infront thereof'between the shuttles and t e recesses K, L, L, to permitthe arm B to pass between the shuttles. The recesses K, L, L, correspondin shape to the projections, G, H, H, and are so constructed that theshuttles 36 are loosely held therein, the projections Gr, H, Hpreventing displacement of the shuttle when a weft thread 29 is passinground it and each shuttle 36 carries a thread which is drawn from thenon-curved end 43, such threads forming a special warp or selvedgethread.

Near the nose ends of the shuttles 36 are positioned twopivoted springcontrolled gates M, M which are primarily intended to divert the threadson to the outside of the shuttles 36 on the return journey of the rod28, after the arms B of the rods 28 in their forward journey have actedupon same and pushed them o en and the springs have returned them to teir normal position.

In operation and after the warp threads P are crossed in the usualmanner before applying the weft' threads, the rod or rods 28 is or areprojected across the fabric E, carrying with Vit or them the weftthreads 29 in the form of loops and then the pivoted arms B pass throughthe opening N and strike the gates M, M open them and pass by them,carrying with them the weft threads 29 the gates M, M closing underaction of the springs and on the return journey the arms B will becomestraightened or nearly straightened out with the rods 28 and the weftthreads 29 will be pulled up against the gates M, M which are preferablycurved or angled, and the threads will ride over same and pass over thenoses F and around the shuttles 36 and under the pmjections` H, H whichloosely fit the holes L in the shuttle carrier, such action carryingth(l loops of the weft threads around their respective special warp orselvedge thread or threads drawn from the shuttle or shuttle 36 wherebythe weft threads are retained at the selvedges of the fabric remote fromthe weft supply. After the return movement oft the rod or rods 28, theusual action ofthe Warp threads takes place. A repeat moveA ment of therods then occurs. lil/what We do claim as our-invention and desiretosecure by Letters Patent is 1- l. lln looms wherein the wefts are drawnfrom stationary supplies, mechanism for operating the weft threadconnarising reciprocatory member, a track for guiding said member, andan arm hinged to said member to carry the weft thread, in combinationwith a selvedge shuttle for the weft thread, a casing 'for the shuttlehaving holes therein, the shuttle having a spring-controlled gate at itsnose end and having projections eX- tending into said holes in thecasing, said reciprocatory member acting on the springcontrolled gate toopen and pass the same and 'carry the weft thread beyond it. during theoutward journey and draw the weft thread loop around the selvedgeshuttle and a selvedg'e thread drawn therefrom during the return journeyof said member.

2. In looms wherein the Wets are drawn from stationary supplies,mechanism 'for operating the wett thread comprising a reeiprocatorymember having a Weit carrying arm pivoted thereon, in combination with ashuttle, and a gatecooperative therewith, the gate being located in thepath of said armY whereby it will be deiieeted thereby When vsaid memberis advanced, and the gate being movable, after said arm has passed it,into a position to deflect the Weit thread around the shuttle duringreturn. movement of said member. Y

In testimony whereof We have hereunto set our hands.
